The most effective methods of birth control are sterilization by means of vasectomy in males and tubal ligation in females, intrauterine devices (IUDs) and implantable contraceptives. This is followed by a number of hormonal contraceptives including oral pills, patches, vaginal rings, and injections.
Strongyloides StronÂ·gyÂ·loiÂ·des (strÅn'jÉ-loi'dÄz) n. A genus of small nematode intestinal parasites that includes the species that causes strongyloidiasis in humans.
1. Strongyloides is a genus of parasitic nematodes. Strongyloides is a genus containing some 50 species of obligate gastrointestinal parasites of vertebrates (Speare, 1989). Strongyloides infects mammals, birds, reptiles and amphibians.Where investigated, most species appear to be able to infect one, or at most a very few, host species.herefore the taxonomic arrangement of Caenorhabditis and Strongyloides is not consistent with the reconstructed phylogeny. Note the difference between the taxonomic order Strongyloida and the family Strongyloidea (order Rhabditida), which contains Strongyloides spp.; a potential source of great confusion. Figure 2.
